Quadrants & Tender Points

The Four Quadrants

The "Fibromyalgia Defined" area pointed out that in order to meet the criteria established by the American College of Rheumatology, the pain must have been present for at least 3 months' duration, and must be present in all 4 quadrants of the body.

What exactly is a quadrant? Imagine dividing the body into four quarters:

(1)
Right side - above the waist
(2)
Left side - above the waist
(3)
Right side - below the waist
(4)
Left side - below the waist
